Problems in the deployment temperature

Zero · December 17, 2013, 01:59

Dear all,

First im sorry if my poor language skills, i have a problem to simulation ansys cfx 2013. I have made an experiment on a cube and I insert an object into the cube. Cube was rather like the room and the object is a machine that has a temperature of 100 Celsius. In my pre CFX-cube into the air stream with a temperature of 25 Celsius and some other settings.

And at this stage of the CFX-post I made sebuat plane and I named plane 1. Variable on the first plane I set it as a base for cross-sectional temperature but the results do not spread on the plane, while if 1 variable on my plane to pressure or viscosity change there will be a deployment on the plane.

If you all have a solution please explanation, thank you..

Can you post some images of what you are seeing, and include your CCL.

yes but may i know your address mail glenn because too large capacity if i send here ?

Is the interface connecting the solid and fluid domains correct?

Is your simulation converged?

Do you need to run it for longer physical time? Convergence of CHT simulations cannot be judged by residuals alone. You often need to add imbalances as a convergence critereon.

Setting Interface

Have you ever done the experiment of heat transfer (CHT)?

Can you show me (tutorial) step by step about to add imbalances as a convergence critereon ?

Do the CHT tutorials provided with CFX. The heating coil is a good one.

Imbalances are an option under convergence control.
